The stars of The Hills were all out in NYC last night to celebrate the fourth season finale of their dramatic show. OK, so maybe I shed a tear or two. Spencer did do the right thing and Heidi was teary most of the episode, so it's justifiable, right? As they walked the red carpet in their finest gear, Lauren fancied up her look with a tucked-under updo, Heidi and Audrina took a more classic approach, and Whitney — she went for a hippie-flower-girl kind of style. So tell me, which of these waved hairstyles is your favorite?
